   Well, if you have a tunable laser, then some mirrors and lens tubes is enough.   
      
   http://www.teachspin.com/instruments/fpc/index.shtml   
   Mirrors come from cvi laser ~$200 each.     
      
   Tunable is harder, without going to piezo electrics,    
   I've thought about tuning with gas pressure or temperature.  (neither are very   
   fast.)
